Patented Aug. 5, 1919.

To all whom it may concern:

Be it known that we, AUGUST MARTIN and HnNnY H. DoiuuNo, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Egg-'lrcating hflachincs, of which the following is a description, reference be ing had to the accompanying drawings,

which form a part of our specification.

Our invention relates to a machine for sterilizing and preserving eggs by immersing them in liquid preparations which are heated to predetermined degrees of tempera- I5 ture the invention contemplating a suitable apparatus, which is preferably manually operated, whereby a number of eggs may be simultaneously treated, as will be more fully comprehended from the following detailed dcscri rlon of the drawin wherein Figure 1 is a partial front elevation and "vertical sectional view of our improved machine.

Fig. S3 s a vertical sectional view, taken on the line .2

of Fig. 1 looking in the posed on the rear side of the machine.

Fig. 4 is a perspective view of a portion of the machine illustrating a modified form of operating mechanism.

Fig. 5 is a vertical sectional view of the construction shown in Fig. 4 looking toward the operating mechanism of the machine.

In the exemplificution of the invention, the machine or apparatus is preferably shown as manuall operated; the machine ails tank portion 10, preferably constructed of metal so as to provide a plurality of fluid-ti ht comp; 'tmi nts "or chambers which are sn jected to heat in order that the sterilizing and preserving fluid contents of the compartments of the tank may be maintained at the desired temperatures.

The tank-portion 10 of the machine 1S preferably of such length as to provide at 5i least a pair of clnunbers or compartments 11 and 12, which are preferably separated from each other by means of an air-chamber or space 13, in order that the compartments may be insulated from each other; or this may be :wcomplislied by any other suitable heatinsulating means. The tank-portion of the machine is mounted on a suitable supporting frame comprising-the uprights or legs 14 formed of angle iron or any other suitable members; the uprights or legs being reinforced and secured together adjacent the lower ends thereof by cross-members 15.

The front side of the machine at a central point. intermediate of the ends is shown provided with a pair of parallellydisposed angle members 16, 16 arranged in slight separatedrelation so as to provide a guidewuy for a foot-treadle or operating lever 17. The foot-treadle is provided at the front of the machine with a suitable foot-rest portion 18 and the trcadle is disposed beneath the tank-portion of the apparatus toward the rear side of the machine where it terminates in, or is connected with, the vertically disposed rod 19 extending toward the top of the machine and opL-ratively secured to a cross-bar or member '20, see Fig. 3.

The vertically disposed rod 19 is preferably square ,in crosssection and made to pass through suitable brackets or guide members 21 and secured to the rear side of the tank-portion of the machine, as shown in Fig. 3; the brackets or guide members 21 and being made to conform with the cross-sectional contour of the rod 19 and thus prevent any possibility of the rod rotating about its own axis.

At a suitable point, to-wit preferably beneath the bracket or guide 21, the rod 19 of the foot-treadle or operating lever is puny Ml vided with a lug or arm 23 shown disposed at right angles to the rod-portion of the foot-treadlc; with the outer end of the lug or arm shown provided with a cross-arm or transversely disposed ln s 24. The ends of the lugs 24 are provide with apertures to receive the ends of the two springs 25, 25 whose opposite ends are secured to suitable members or eye-bolts 26 extending through suitable a ertures in the bars or frame members 27 w ich are secured to the cross-bar or frame member 28. The cross-bar 28 is maintained in osition by suitable uprights or rods 29 w rich are secured in any suitable manner to the rear side of the tank portion 10 of the machine. The eye-bolts or members 26 may be vertically adjustcdjn the apertures in bars 27, by screwing the same throu h the nuts with which their threaded on s are provided; the nuts being preferably disloo posedbn both sides of bars 27, thus enabling the tension of the springs 25, 25 to be increased or decreased as desired; the springs being adapted to draw the rod 19, and therefore also foot-treadle 17 upward into the raised and normal position of the operating mechanism shown in Fig. 2. The u'ward movement of the treadle will be limi ed by contact of the cross-bar or member 20 coming into contact with crossbar or member 28.

Each compartment or chamber 11 and 12 is provided with a skeleton tray or plunger member 30 the trays 30 being secured to upright straps or bars 31. The upper ends of these straps or bars are shown bent rearwardly. see Figs. 2 and 3, and provided with apertures for the passage of posts or supporting members 29 abroad with the apertures.

The trays or plunger members 30 consist of open rectangular frames provided with angle-bars 32, 32 arranged in. parallel relation aCIOSS the top from side to side to provide a guide-way and support for a suitable wire-basket or foritminated egg-holding container not shown, and which has previously been filled with the eggs to be treated; the baskets or containers whencharged being placed on the stationary shelves 33 arranged at the ends of the ma-.

chine, adjacent the top of the tank-portion. The shelves 33 we so ositioned as to enable the baskets to be sli onto the guide-ways 32 of the trays or plunger members 30; the bars 32 insuring the proper placing of the baskets to permit operation of the machine.

I order to reinforce and properly support the forward side of the tray or plunger member 30, we have shown the strnps 31 extending slightly below the tray or open frame of each compartment. with the lower ends provided with the diagonally disposed brace members 34 which extend forward and are secured to the front side of the traysv or open frame, as shown in Fig. 2.

Disposed longitudinally beneath the tankortion of the machine, and therefore beneutb the chambers or compbrtments 11 and 12, are 1. plurality of burners 35 which are adapted to be connected with nnysuitable source of gas supply, controllable by suitable keys or valves, as shown at 36 in Fig. 1.

In practice, the solution or liquid contents of the one chmnbcr or compartment is intended to be heated to e greater degree of temperature than the temperature of .the contents of the other chamber or compartment, and for that reason the one chmnber need merely lmve two burners therebenimih, while the other chamber preferably has all of the burners disposed beneath the sumo.

In order that the temperature of the fluidcontents of the different chambersor compartments may be ascertained, each tank und is shown provided with a suitable thermomc' ter. as at 37. arranged at a point where it will not interfere with the proper operation of thebasket-carrying tray or plunger member; the thermometers being provided with portions depending into the chambers or compartments and therefore into the fluid contents or solution.

The chambers or compartments, :uljncent the bottoms thereof, are. preferably provided with a suitable drain or outlet which may be in the nature of the drew-off cock or faucet shown at 38 in Fig. 2, whereby the contents of the chambers may be withdrawn when desired.

As is evident from the construction shown and described, a downward pressure on tho foot-lever or treadle'li' will cause the latter to move downwardly against the actions of the springs 25; and as the foot-lever is secured to the cross-member 20, to which the basket-carrying members or trays 30 are so" cured by the straps 31, the downward move ment of the foot-lever will cause both basketourrying members or trays 30 to descend into their respective chambers or compartments: the bars or straps of the basket cztrrying members or trays, together with cross-membe! 20, having guiding and sliding relation with the rear wall of the tank and the supporting members or rods '29, as; previously described.

In Figs. 4 and 5, we illustrate a. modified form of the machine. wherein the tank con- 'struction and its manner of support is sub stnntiully similar to the construction shown in the first figures of the drawings, with the tank portion 39 divided into several coinpartments or chambers having an intervening air space beneath the top portion of the tank at the point indicated, at 13, similar to the construction shown in Fig. 1 In this construction the basket-carrying members or trays 30 are secured to the straps 40, 1|, pair of .straps being preferably employed for each tray or besket-carryin plunger. The per ends of the straps 0 are bent into the loop form shown in the drawings, so as to have a leg of each strap or band disposed parallel with and on opposite sides of the tenkportion 39 of the machine.-

The rear side of the machine is provided with suitable brackets or guides 41 and the lower outer ends of ,the straps 41 are connected together by means of it suitable bar 42 so as to cause both straps l0, and therefore both trays orbnsket-carrying plungcrs 30 to move in unison. Y

Pivotally secured, at an intermediate point to the bar 42, is a. link 43 which, in turn, is-pivotally secured to a lever 44 dis.- osed beneath the machine and pivoted at its forward end atthc point 45 so as to permit vertical movementof thelevernbout the pivotal point-'15. V The rear end of the lever p which nan has through a suitable aperture in the of the *fnachme,

-turn of the plunger or v or plunger of 44 extends beyond the point of its pivotal connection with link 43, and is there provided with a suitable coil spring 46, the

other end of which is secured tca an eye-bolt or other suitable adjustable member 47, adjustable relation w th a bracket or angle member 48 by means of butter-fly nut 49; the eye-bolt 47 'assing racket member 48 which is secured to the rear side of the machine. At a point centrally be tween the endsof the machine and in vertical alinement with the lever 44, we provide a foot-treadle or lever 50 which is pivotally secured in any suitable manner, at 51, on the supporting frame of the machine; with the foot-receiving portion 52 extending forward as'shown in Fi 5. e foot-treadle or lever 50 is *operatively connected' with lever M by means of a suitable link 53; and the upward movement of thefoot-tr'eadle', beyon a predetermined point, is limited by a suitable strap or cross-bar 54, see Fig. '5. It is evident from this construction that downward pressure on the foot-treadle 50 will cause lever 44, through the medium of link 53, to be drawn downwardl against the action ofspring 46 and there ore also cause the 'egg plungers or tra' s 30 to descend into their respective c ambers or compartments through the medium of straps. 40 which have connection at their lower ends with the lever 44; the trays or basket-carrying plungers being cause to move in unison.

Our improved machines, as previously stated, are especially intended for carrying out a process of preserving eggs, which contemplates the immersion of t e eggs (previously placed in suitable baskets-or containers; in; suitable solutions whereby the eggs are sterilized and provided with a suita le sealing coating without afiecting the qllliality of the eggs: In order to carry out t is process, it 1s necessary to immerse the eggs and for that reason one of the compartments of the tank portion of the machine, 'as' for example chamber or compartment 11, with its liquid contents, is heated to a prede tel-mined degree ottem or basketlonger of t is chamber '18 depressed so as to immerse the eggs for a brief .period of time in order that the same may be prepared or tempered; and immediately thereafter the egg-filled basket, upon the retray to normal posiis shifted onto the basket-carrying tray the adjacent chamber or comtion,

artment, as for example-chamber .12 in. the foot-trundle orlever is ig. 1, when again depressedanithe eggs lowered into the second chamber or compartment which 'iS provided with a suitable solution,

difljo a pf temperature than the operating basket-carrying 7 in solutions of different temperatures rature. The/tray;

m their respective c heated solutionin the first mentioned compartment on chamber; the tray being maintained in machine, it is evident th tthe first-mentioned tray may be suplp led with a fresh supply of eggs before t e eggs on the tra of chamber 12 are immersed, so that can tra or basket-carrying plunger will be provi ed with e gs, and a sing e operation of the foot-tree. le or lever will result in the initial tempering as well as in the final treatment and coating of the eggs.

As the immersion of the eggs ust continue for a very short predetermined period, the machine is preferably shown as manually operated so as to be under the full control of the operator. In view of the fact that the chambers or compartments of the tank must be heated, the tank portion of the machine is referably formed of suitable metal; whi e the construction of the mechanism is such that but little power need be exerted by the operator to manipulate the trays or plunger elements, which are automatically returned to normal position; the trays or plungers being maintained in proper alinement by the means whereby the trays or plun rs are connected with the foot-treadle or ever of the machines. The chambers or compartments of the tank are preferably shown separated by the air space or chamber 13, in order that the temperatures of the two chambers and their contents may be maintained at different degrees without the heat of the one being conducted through the adjacent metallic walls.

The constructions that have been shown and described may be varied in certain details without, however, departing from the spirit of our invention.
